All I see is that Emacs tried to display a tooltip.

Hmm... so the short tooltip text somehow causes us to exceed the
number of glyph rows of the matrix? Please tell what the commands
below show:
(gdb) pgrowx it->w->desired_matrix->rows
(gdb) pgrowx it->w->desired_matrix->rows+1
(gdb) pgrowx it->w->desired_matrix->rows+2
(gdb) pgrowx it->w->desired_matrix->rows+3
...
(gdb) pgrowx it->w->desired_matrix->rows+34
That is, I want to see the entire contents of the glyph rows.
Also
(gdb) p it->last_visible_x
(gdb) p it->last_visible_y
Thanks.
